Klarna vs Afterpay: A Detailed Comparison
Two BNPL giants compared on merchant fees, consumer experience, and market coverage.
The Buy Now, Pay Later (BNPL) market is dominated by two providers: Klarna (Swedish, founded 2005, 150M+ active consumers) and Afterpay (Australian, founded 2014, now owned by Block, Inc., operating as Clearpay in the UK). Both enable consumers to split purchases into interest-free installments, but they differ significantly in geographic coverage, merchant fees, and consumer features. For merchants choosing between Klarna and Afterpay, the decision comes down to target market, order value profile, and integration ecosystem.

Key Differences
1. Geographic Coverage
Klarna has broader global reach, operating in 45 countries across Europe, North America, APAC, and select emerging markets. This makes Klarna the better choice for merchants selling internationally or operating in European markets where Afterpay has limited presence.
Afterpay (including Clearpay in the UK) focuses on four core markets: the US, UK, Australia, and Canada. Afterpay's geographic footprint is narrower, but its integration with Block's Cash App ecosystem provides a strong consumer base in these markets.
2. Payment Products
Klarna offers three distinct products: Pay in 4 (interest-free installments), Pay in 30 Days (invoice with no upfront payment), and Financing (structured monthly payments for 6–36 months). The invoice option (Pay in 30 Days) is a unique differentiator that resonates strongly with European consumers.
Afterpay offers two products: Pay in 4 (interest-free installments) and Monthly (structured payments for longer terms). Afterpay does not offer an invoice/pay-later option.
3. Merchant Fees
Klarna charges merchants between 3.29% and 5.99% per transaction plus a $0.30 fixed fee, depending on the payment product, region, and transaction volume.
Afterpay charges merchants between 4.0% and 6.0% per transaction plus a $0.30 fixed fee. Afterpay's merchant fees are generally higher than Klarna's, particularly for high-volume merchants.
4. AOV Lift
Klarna reports a typical average order value (AOV) increase of 40–60% when Klarna is offered at checkout — the highest AOV lift among BNPL providers.
Afterpay reports a typical AOV increase of 20–30%, which is meaningful but lower than Klarna's impact.
5. Consumer Features
Klarna provides a comprehensive shopping app that aggregates deals from partner merchants, drives consumer traffic, and includes price-drop alerts, loyalty rewards, and a virtual shopping card.
Afterpay integrates with Block's Cash App, providing Afterpay access to Cash App's 50M+ users. Afterpay also operates a merchant discovery platform within the Cash App ecosystem.
UK Market: Klarna vs Clearpay (Afterpay)
In the United Kingdom, Afterpay operates under the Clearpay brand. The UK BNPL market is the most competitive in Europe, with Klarna, Clearpay (Afterpay), and Laybuy all competing for merchant and consumer attention.
For UK merchants evaluating BNPL providers, the choice between Klarna and Clearpay depends on:
- Consumer demographics: Klarna skews slightly older (25–40) with higher AOV; Clearpay skews younger (18–30) with social-media-driven discovery.
- Brand awareness: Klarna has stronger UK brand recognition (driven by advertising spend); Clearpay benefits from Cash App integration.
- Merchant fees: Klarna's UK rates are generally 3.29–5.99% + £0.20; Clearpay charges 4.0–6.0% + £0.30.

When to Choose Klarna
- European expansion: Klarna's 45-country coverage and strong EU market position make it the default choice for merchants selling across Europe.
- Higher AOV products: Klarna's 40–60% AOV lift is most impactful for merchants selling $100–$500 products where installment payments significantly reduce purchase friction.
- Invoice option: Merchants selling to consumers who prefer pay-later/invoice options (common in EU, Nordic markets) benefit from Klarna's Pay in 30 Days.
- Consumer acquisition: Klarna's 150M+ active consumers and shopping app drive new customer traffic to partner merchants.
When to Choose Afterpay
- US, UK, Australia focus: If your merchant operations are concentrated in these four markets, Afterpay's Cash App integration provides a strong consumer base.
- Gen Z audience: Afterpay's social-media-driven discovery and Cash App ecosystem resonate strongly with younger consumers.
- Existing Block ecosystem: Merchants already using Block's Square POS or Cash App Pay may find Afterpay integration seamless.
- Simpler product set: Afterpay's two-product approach (Pay in 4 + Monthly) is simpler to integrate and explain to consumers.
Integration Considerations
Both Klarna and Afterpay integrate with major e-commerce platforms (Shopify, WooCommerce, Magento, BigCommerce) and payment processors (Stripe, Adyen, Braintree). Integration effort is comparable — both provide SDKs, plugins, and pre-built checkout elements.
For merchants already integrated with Stripe, enabling both Klarna and Afterpay at checkout is a configuration change rather than a separate integration. Stripe supports both providers natively.
FAQ
What is the difference between Klarna and Afterpay?
Klarna and Afterpay are both BNPL providers, but they differ in geographic reach (Klarna: 45 countries; Afterpay: 4 core markets), payment products (Klarna adds invoice and financing), merchant fees (Klarna is generally lower), and AOV lift (Klarna: 40–60%; Afterpay: 20–30%). Klarna is stronger in Europe; Afterpay is stronger in the US/UK/Australia via Block's Cash App ecosystem.
Which is cheaper for merchants — Klarna or Afterpay?
Klarna's merchant fees (3.29–5.99% + $0.30) are generally lower than Afterpay's (4.0–6.0% + $0.30), particularly for high-volume merchants. However, the cost comparison should be evaluated against AOV lift — Klarna's 40–60% AOV increase may offset higher fees through increased revenue per transaction.
